High voltage in noble liquids for high energy physics

High-Energy Physics

High Energy Physics,horizons*

The previous sessions have borne witness to the fact &at high energy accelerator and storage ring technology is a.subject of continuing vitality. Nothing dramatizes this more convincingly than the chart (Fig. 1) which shows the growth in energy of the world’s accelerators in time. If one includes in this chart the equivalent laboratory energy of existing and projected colliding beam storage rin...

High Energy Physics GRID

Computing is one of the technologies associated to High Energy Physics (HEP). The needs of the next generation CERN HEP experiments push the development of new computing architectures. The scale of data will be orders of magnitude larger than the one we currently have. In this talk we will present the current status of GRID computing development.

High Energy Astroparticle Physics

We give a brief (and highly incomplete) overview of the current experimental and theoretical status of high energy cosmic rays and their secondary γ−rays and neutrinos. We focus on the role of large scale magnetic fields and on multi-messenger aspects linking these three channels. We also recall that the flavor composition of neutrino fluxes from astrophysical sources contains information on bo...

High-resolution electro-magnetic calorimetry with noble liquids

Electromagnetic calorimeters with noble liquids and their limits in resolution are discussed. The origins of “initial” current measurement in calorimetry are retraced and the performance and first results of the NA48 calorimeter (quasi-homogeneous calorimeter with longitudinal electrode structure) are presented. Results of the prototype calorimeters of KEDR (quasi-homogeneous calorimeter with t...
